twisting to make it stifi enough to transmit energy to the shaft 6. As the disk 5 is tightening the spring 14, it must move more or less to the left on the shaft 6 so long as this shaft and the said disk are not rotating at the same speed, as is apparent to one ski] led in the art.

As the friction disk 5 is movin to the right along the shaft 6 under the in uence of the spring 14, the friction disk 4 is also moved to the right, and this friction disk 4 will. cease to have lon itudinal movement on the shaft 2 when the fiiction disk 5 ceases to have longitudinal movement on the shaft 6. It will be understood by one skilled in this art that the further the friction disk 4 is nioyed to the right, the faster will the fricfianges 12 and 13 formed respectively with the friction-disks 4 and 5. By means of the construction just described, the frictiondisks t and 5 are always held a constant distance apart.

1/1 is a spring mounted to surround a port-ion oi. the length of the power-consuming shaft 6, and one end 1.? of this spring is secured by any suitable means, (such as the U-shaped clamp 16 extending through the hub 17 of the friction disk 5) to said friction disk; Locking said clamp in position are nuts 18.

Splined on the newer shaft 6 is a member 19 comprising a isk 20 to which the end 21 of the spring 14 suitably secured, preferably by means f the same construction whereby the end15 of the said sprin is tion disksC be revolved, and that the furclamped in position. The disk 20 is rovided er the friction disk 5 is moved to the ri ht, with a hub 22 ,integrally provide with a the faster will the same be revolved. I he hlch spaced apart from the disk 20 by means of the annular groove in. which is clamped the two-part ring 24 comprising sections 25 and 26 which are bolted together at their ends by the nuts and bolts designated by thecommon numeral 27. The the right the operator moves the disk 19 two-part ring 24 allows the disk 20 and its along the shaft the higher will be the connected parts to freely rotate. I'ntespeed obtained,- as wlllbeunderstood by one grally formed ,with the section 25 is a post s Killed in this art. Whenever the road re- 28 through which passes a bolt :29 held sistance or the resistance encountered by the therein. power-consuming shaft 6 in'doing work is As before described, the motor B, when too great for the pen er developed by the the vehicle or machine is in use, is'always torque, there naturally will be a lag in the operating at full speed and. developing full P WOI CODSUIUIlDg-Shaft G- and the d k power. In the position of the parts illusphned thereon. Now, as a result of this trated in the drawings, the friction disk 5 is g, d by Peat-0f! 0f the colwtlol} w n positioned o posite the center of the friction the threads of the hub 38 of the disk 5, and disks C, ant consequently the vehicle is at the disks 5 'and 4, rest. In order to start the vehicle, the driver, by means of the lever 30 pivoted near his seat, and connected by the rod 31 with the bell-crank lever pivoted at 33 to the bearing-member 35L 0 the frame A) moves this bell-crank lever in the direction inclicated by arrow, and as the bolt 29 operates in the slot formed in theeud 36 of this lever, the disk 20 and its connected parts are moved to the right on the power-consuming described longitudinal movments of the friccollar 23 w will be quite gradual, and consegu'ently the shaft 6 will be turned slowly at rst and s0 prevent any undue jarring. The farther to the splral groove 3i coupled together'by the will be moved to the left across each face of the disk (7 until the speed of the mechanism has been reduced and the power of the torque'increascd enough to overcome theresistance. To allow for this movement, the spring 14, must readily le'n then, as will he understood, use, of course the spring 14 not under any strain. It will of course be understood that shaft This shaft (5 is provided with a by means of the lever 30 and its connected spiral-groove with which engage threads parts, the bell-crank lever 32 Will woven formed in the hub 58,01? the disk 5. The i longitudinal movement of the disk 20 on the shaft 6.. T he friction disks 4 and 5 are preferably faced with leather a or other suitable material, so asto increase the friction said spiral groove is shapcdthat t-he said disk 5 may be readily shifted by the spring 14 to the right. 1

' As a result ofthe described movement, the between the same and the disks C.

coils of the spring 14 pull the disk 5 to the J In order to brake the vehicle, or cause the lighten the shalt 6, the desired distance, same to run backward, the bell-crank lever determined by the operator. Immediately 32 ishwvedby the lever 30 and rod 31 in the disk comes into contact .With the. disks,

C, it starts to rotate, and in due course the spring 1-1- is twisted stilt? enough to transmit energy to the shaft *3 which. will operate the the arrow, and so moves the disk 5 to the let'thand side of the center of the disks C, thus getting a rotation of the disk 5 1n the dit rentiai gearing and drive the dire ion indicated by the plain arrow. It mounted on their lore follows that 1f the disk 5 be mainwheels aha much I tained in the position just described for a tion disks4 and 5 on their respective shafts connecting sleeve 9,
